You were then assigned p p 562 17,18 as well as #4 and 5 from the worksheet(18.3 solubility equilibrium)
Answers for #5 Ag + = 1.9 x 10 ^-6 mol/L
Also from your text please do 20 to 25 on p 565 and 19, 20 p 564.
. At the top of the page of the handout for this chapter, there are some review questions(#1-7) from 18.1,18.2 and 18.3. These should be done for review. ..please note that 1 and 2 are actually all a part of the same question.
MH here are some notes
.See the answers to your quiz from yesterday...see what we are doing tomorrow..read ahead to thursday's class work We went over precipitation calculations today. Please do 6, 7 from the worksheet and from the text p 565 26, 27.
We went over last night's homework. Here are the solutions to the quiz from yesterday

Mar 14-Friday Day 25
Chem 112- Properties assignment is due today. Quiz on monday on both the molecules to study and the diatomic molecules and polyatomic molecules
We are now going to deal with the last family the ionic hydrates. They are ionic but have water molecules attached. From the long sheet you did 6 and 7 in class on naming and writing the formulas for hydratesWe overviewed properties of compounds/molecule/ionic/acids/bases.
Sheet 7 and 8 from the pink handout should be completed for monday.
We will also do a quiz on molecular names/formulas from the back of your acid/bas/salt sheet.
